Electronic intermediaries have become pervasive in sales transactions for many durables, such as cars, power tools, and apartments. Yet only recently have they successfully tackled the challenge of enabling parties to share such goods. A key impediment to sharing is a lender's concern about...

Sharing markets create mutual insurance for consumers who are unsure about their future needs for goods, thus rendering products more valuable both before and after the purchase. By embedding intelligence in their products, enabling them to sense, monitor, and authorize transfers between users,...

The collaborative-housing market fails when agents' hidden actions are non-contractable....

This paper studies the price discovery dynamics in an order-driven market. Based on the transaction data on individual stocks, the paper focuses on the study of the monthly evolution of normalized volatility ratios on Euronext Paris for the CAC40 stocks before and after the implementation of the...
